How do you score a 50 in the slam dunk contest for NBA live 08 for xbox?

Well on the psp I know a couple.

1. hold down the L & R buttons plus O for your gather ( the player will do a cart-wheel) then push the O button again he will put it in between his legs twice ( let go after he goes through once) a 50 every time.

2. Hold down the L & R buttons plus the square button for your gather then push the O button he will go behind his back (If timed perfectly a 50 but I've never got less than a 48)

Hold L2 and R2 all the time, take off using 0 and then 0 again, hanspring under the legs twice, 50 on its own or you can do it alley-oop style just for the hell

also alley-oop off the backboard, x then triangle (L2 and R2 for both) slam it and hang from your elbow, another 50
